STOP-INDICATOR FOR LOOMS.

SPECIFICATION formingpart of Letters Patent No. 616,055 dated December 1898- Application filed June 16, 1898. Serial No. 683,594. (No model.)

To all whom it may concern:

Be it known that I, WILLIE G. EATON, of Nashua, county of I-Iillsborough, State of New Hampshire, have invented an Improvement in Stop-Indicators for Looms, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

In modern textile mills it is customary for one weaver to tend a number of looms, the weaver going from loom to loom to see that each is operating properly, and in the case of looms provided with automatic filling-supplying mechanism the weaver attends to from sixteen to twenty or more looms. When a loom stops for any cause, it is of course desirable that the weaver shall discover the fact at the earliest possible moment in orderthat the cause of such stoppage may be removed and the loom started up again.

This invention has for its object the production of a simple and edective stop-indicator for looms, whereby the stoppage of a loom is instantly indicated to the weaver and the particular loom of the group located.

Owing to the noise in a weave-room I prefer to make use of a visual indicator, mounted on the loom in such manner as to be moved into indicating position only upon stoppage of the loom, the loom being thus easily and instantly located by the eye of the attendant.

Figure 1 is a perspective view of a sufficient portion of a loom to be understood with one embodiment of my invention applied thereto, and Fig. 2 is a detail in elevation to be referred to.

Theloom-frame A, shipper-lever S, fast and loose pulleys B B, and belt fork or shifter 13 may be and are all of well-known or usual construction in looms, the belt-shifter being shown in full-line position, Fig. 1, opposite the loose pulley B.

As herein shown, I have mounted on the arch A of the frame, and preferably at the rear side thereof, a rod or staff a, pivoted at its lower end on a pin or stud a Fig. 2, and carrying atits free end a flag or visual indicator F of any suitable construction. The

staff a is provided at its lower end, adjacent its fulcrum a with a rocker-arm a, and this arm is pivotally connected by a link a with some part of the stopping mechanism which occupies different positions when the loom is at rest or running. Herein I have shown the link a connected with the belt-shifter B, so that when the latter moves the driving-belt (not shown) onto the loose pulley the indi cator F will be moved up into full-line position, Fig. 1, above the arch and in full view of the weaver. When the loom is started, the movement of the shifter into dotted-line position will depress the indicator back of or to be practically hidden by thearch A and while the loom is running the indicator will be maintained in such position.

My invention is very simple and effective, takes up but little room, and it can be readily and cheaply applied to any loom.

The location of the indicator may be varied and the construction and arrangement herein shown may be changed without departing from the spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a loom, stopping mechanism, including a belt-shifter, avisual stop-indicator, and operating connections between the indicator and thebelt-shifter, whereby said indicator will be moved into non-indicating position when the loom is started, and maintained in such position while the loom is running and moved into abnormal visible position upon stoppage of the loom.

2. In a loom, stopping mechanism, including a belt-shifter, a visual stop-indicator pivotally mounted on a fixed part of the loom and provided with a rocker-arm, and a link connecting said arm and be1t-shifter,whereby movement of the latter to start or stop the loom will automatically move the indicator into non-indicating position or into visible, indicating position respectively.

3. In a loom, a visual signalpivotallymounted on a fixed support and having an attached rocker-arm, stopping mechanism for the loom, and a link connecting a movable part of said mechanism and the rocker-arm, to move said signal into indicating or non-indicating position, upon stoppage or starting of the 100m respectively.

4. In a loom, the arch, a signal-flag, its staff pivotally mounted on the arch to be hidden thereby when the 100m is running, stopping mechanism for the 100m, and a connection between the flagstaff and said mechanism, to

:0 automatically move the latter into indicating position above the arch upon stoppage of the 100m.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

XVILLIE G. EATON.
